Commission Calculation to arrive GST

Commission Calculation to arrive GST

We are setting up our zoho books, Our service is air ticket, air ticket rate (total fare) is divided into 4 breakups

Basic Fare
Airline Surcharge
Other Taxes
K3

Basic Fare + Airline Surcharge + Other Taxes + K3 = Total Fare

How to setup this in zoho books, so that it can reflect in estimate, bill, purchase order and invoice.

Thanks in advance
